(12)/(x+3)=2

\frac{12}{x + 3} = 2

x = 3

Solution steps

\frac{12}{x + 3} = 2

Multiply both sides by

x + 3

12 = 2 (x + 3)

Switch sides

2 (x + 3) = 12

Divide both sides by

2

x + 3 = 6

Move

3

to the right side

x = 3

Verify Solutions

Find undefined (singularity) points:

x = - 3

Combine undefined points with solutions:

x = 3

y, x = \frac{6 y + 4}{4 y + 5}

\frac{4}{3 x - 4} = 5 + x

\frac{4 x}{x} = \frac{10}{4}

\frac{3}{2 x} = 5

- 3 = \frac{3 x ^{2}}{8 x + 5}
